“…XRD pattern of Ni(OH) 2 . Figure 4b is in good agreement with the standard pattern of Ni(OH) 2 and pattern reported for Ni(OH) 2 nanoparticles [20][21][22]. The observed peaks appreciably broad indicating that the as synthesized Nickel hydroxide nanoparticles are crystalline in nature with hexagonal phase.…”

Nickel oxide nano crystallites were synthesized using Nickel [II] Chloride and Sodium hydroxide. The Thermo Gravimetric and Differential Thermo gravimetric (TGA/DTA) analysis were done to study the thermal behavior of the as synthesized sample Ni(OH)2. The peak at 290°C in DTA may be related to the decomposition of Ni(OH)2 into NiO. The structural, optical properties, morphology and composition of NiO nano particles (NPs) were studied by various techniques such as XRD, FTIR, UV-Vis, PL, FESEM and EDAX. The antimicrobial activity were carried out against Gram positive and Gram negative bacteria and NiO NPs showed inhibitory activity in both strains of bacteria with excellent selectivity against Gram-positive bacteria.

“…The broadness of this band indicates the presence of NiO nanocrystals in the prepared samples. The observed vibration band for all the samples is wellconsisted with the literature reported vibration band of NiO [38]. The small double peak at 2362 and 2346 cm -1 is caused by the presence of CO 2 molecules.…”

Composite-hydroxide-mediated (CHM) approach was used to synthesize NiO nanocrystals. The proposed method makes use of molten composite hydroxides; providing reaction media and lower the process temperature. Processing temperature and reaction time are the two potential parameters to control the growth of a nanomaterial. The method was used at temperatures in the range of 180-250°C and formation of the nanomaterial was monitored using XRD, SEM, EDX, FTIR, and UV-visible spectroscopy. The produced nanomaterial was purely polycrystalline with an average crystallite size in the range of 23.71-36.92 nm. Method suggested formation of pyramid shaped NiO nanocrystals in the temperature range 220-250°C. Evidence on the elemental composition, purity, and chemical bonding were obtained from EDX and FTIR analysis respectively. Estimation on direct bandgap was made from the optical analysis and found to be in the range 4.0-4.8 eV. The method is attractive and seems a cost effective route for the growth of transition metal oxides for research purpose. For further efficacy, the approach can be examined for other technologically significant nanostructures.

“…All these spectra show a strong absorption in the 600-400 cm −1 range. This absorption corresponds to the Ni-O stretching of the NiO structure [28,29]. Two peaks can be observed at ~3450 cm −1 and ~1443 cm −1 , which could be attributed to the O-H stretching and bending vibration of water molecules [29].…”

Rare Earth-Promoted Nickel Oxide Nanoparticles as Catalysts for N2O Direct Decomposition

et al. 2016

Abstract:For this paper, a series of rare earth (Gd, La, Sm) promoted NiO catalysts were prepared by using the microwave-assisted precipitation method and tested for N 2 O direct decomposition. The obtained solids have been characterized by using various techniques. X-ray diffraction (XRD) results revealed that the incorporation of RE oxides into NiO significantly decreases its crystallite size. Field-emission scanning electron microscopy (SEM) and transmission electron microscopy (TEM) observations indicated that the addition of RE oxides swells the NiO particles yielding particles into a rice-like morphology. N 2 adsorption studies showed a sharp surface area increase as well as mesoporosity development accompanied the RE incorporation. It was found that the RE oxides significantly enhance the NiO activity.
